= CSV Builder The CSV Builder Rails plugin provides a simple templating system for serving dynamically generated CSV files from your application. == Requirements CSV Builder requires Rails v2.1. It also depends upon the FasterCSV gem http://fastercsv.rubyforge.org, which you can install with $ sudo gem install fastercsv == Example CSV template files are suffixed with '.csv.csvbuilder', for example 'index.csv.csvbuilder' Add rows to your CSV file in the template by pushing arrays of columns into the csv object. # First row csv << [ 'cell 1', 'cell 2' ] # Second row csv << [ 'another cell value', 'and another' ] # etc... You can set the default filename for that a browser will use for 'save as' by setting <tt>@filename</tt> instance variable in your controller's action method e.g. @filename = 'report.csv' You can also set the input encoding and output encoding by setting <tt>@input_encoding</tt> and <tt>@output_encoding</tt> instance variables. These default to 'UTF-8' and 'LATIN1' respectively. e.g. @output_encoding = 'UTF-8' You can also attach a csv file to mail sent out by your application by including a snippet like the following in your mailer method attachment "text/csv" do |attachment| attachment.body = render(:file => 'example/index.csv.csvbuilder') attachment.filename = 'report.csv' end You can change the separator character and that is as simple as writing this in your controller's action method: csv_builder :sep => ';' Actually, all default FasterCSV options can be overriden thanks to the previous statement.
